When the emitter is placed inside the enclosure, the Daubert VCI's seek the metal surfaces inside the packaging or enclosure environment and form a protective molecular layer on the surface of the metal. This layer prevents moisture, hydrogen sulfides, salt, dirt, oxygen, and other contaminants from depositing on the metal and causing damaging corrosion.

Each unit prevents metal corrosion, in an enclosure of 10 cubic feet, for up to 2 years. Daubrite-10 VCI emitters come with a convenient ready to use label for recording the date of installation. Replaces Cortec part VpCI-111
